Abstract
The invention discloses a pneumatic automatic drip-feed instrument which relates to a medical inspirator feeding drips with pressure. The invention is to provide a pneumatic automatic drip-feed instrument capable of automatically stop feeding drips without suspended drip bottle when the drips in the drip bottle is totally fed. The technical proposal of the invention is that a pneumatic automatic drip-feed instrument includes an air supply pump and a drip-feed pipe; a drip switch in the drip-feed pipe at the joint of the drip-feed pipe and the drip bottle is serially connected to a circuit between the air supply pump and a power supply. The drip switch consists of two conducive metal wires in the drip-feed pipe which are not connected; the circuit between the air supply pump and the power supply is provided with a manual automatic reset switch which is parallelly connected with the drip switch. The invention is applied in drip feeding.
Description
Technical field:
The present invention relates to a kind of with pressure transfusion and injector for medical purpose, particularly a kind of Pneumatic automatic transfusion device.
Background technology:
The patent No. 200620031560.4 Pneumatic automatic transfusion devices, because it has adopted gasing pump, to there be the gas of certain air pressure to be passed to and makes liquid import liquid to the patient in the liquid bottles, and overcome existing transfusion device and relied on the shortcoming of the gravity of high suspension bottle to patient's transfusion with certain speed.Yet this transfusion device can not stop transfusion voluntarily when liquid drips off, must be changed liquid bottles rapidly or be extracted syringe needle by the nurse, has an accident otherwise can cause gas to enter in patient's body.
Summary of the invention:
The purpose of this invention is to provide a kind of Pneumatic automatic transfusion device of infusing of stopping automatically when not needing high suspension bottle and the liquid in the liquid bottle to be totally lost.Technical scheme of the present invention is, a kind of Pneumatic automatic transfusion device, comprise gasing pump, tube for transfusion, it is characterized in that: the liquid switch in the tube for transfusion of the junction of tube for transfusion and liquid bottle is serially connected on the circuit between gasing pump and the power supply, this liquid switch is made up of two conductive wires that are not connected that are located in the tube for transfusion, is provided with a manual self-resetting switch and aforesaid liquid switch and is in parallel on the circuit between gasing pump and the power supply.Be provided with a normally closed switch on the circuit of buzzer, armature is relative with a contact of described normally closed switch, liquid switch and and the circuit of its manual self-resetting switch that is in parallel be serially connected on the circuit between armature coil and the power supply.The present invention has compared with the prior art at the liquid of liquid bottle and is totally lost and liquid in the tube for transfusion can stop the remarkable advantage of infusing when not being totally lost automatically.
Description of drawings:
Fig. 1 is a Pneumatic automatic transfusion device structural representation of the present invention, and Fig. 2 is that Pneumatic automatic transfusion device of the present invention is controlled electrical schematic diagram automatically.
The specific embodiment:
The present invention is further described in conjunction with above accompanying drawing, and infusion bottle is placed on the support 6 of transfusion box 1 shell, and the two ends of appendix 8 are connected with infusion bottle 7 with gasing pump 10 respectively, and an end of one-time infusion tube 3 is connected with infusion bottle.Operational approach of the present invention and control principle are, decontrol the regulating wheel 2 on the tube for transfusion, at first by manual self-resetting switch button 5 or delay switch, gasing pump 10 work are the filtering clean air of input process filter in infusion bottle 7, liquid begins to discharge from the syringe needle of tube for transfusion, the nurse lunges syringe needle in the patient's vein blood vessel, adjusts regulating wheel 2 and infuses to the patient with certain speed.Control principle of the present invention is, when normal infusion, normally closed switch 12K2 connects the circuit of voice prompting device 11, and armature movement is with verbal cue device 11 (perhaps buzzer) circuitry cuts.After liquid in the liquid bottles dripped off, when the no liquid of tube for transfusion upper end, liquid switch 5K1 disconnected, armature 13 dead electricity, and switch 12 auto-closings on the verbal cue device circuit send prompt tone (or buzzer) this moment, remind the nurse to change the liquid bottle or extract syringe needle.Prevent that gas from entering in the blood samples of patients and accidents caused.
